Understanding Color in Kyanite
Kyanite’s color is influenced by the trace elements within its crystal structure, with iron and titanium often contributing to its rich blue tones. The presence of chromium can lead to green kyanite, while other elements can produce the rarer orange and yellow varieties. The color of kyanite is an intrinsic part of its identity and desirability.
The Color Grading Chart
1. Deep Blue
Deep blue is the most classic and sought-after color in kyanite. This shade is often compared to the deep blues of sapphire. In the color grading chart, deep blue kyanite is at the top, representing the highest value and demand. The intensity and saturation of the blue color are key factors in its grading, with richer and more uniform hues fetching higher prices.
2. Vivid Blue
A step below deep blue, vivid blue kyanite still offers a striking color but with a slightly lighter tone. These gems possess a lively brightness that makes them highly desirable. The presence of vivid blue coloration with minimal inclusions or color zoning can significantly enhance the gemstone’s value.
3. Green
Green kyanite, ranging from pale to rich forest greens, is prized for its earthy and serene hues. While not as commonly sought after as blue kyanite, green varieties hold a special place for collectors and those looking for unique gemstone colors. The value of green kyanite can vary widely, depending on its clarity and the depth of its color.
4. Teal or Blue-Green
Teal or blue-green kyanite is a rare and intriguing blend of blue and green tones, offering a unique color that appeals to collectors and designers looking for something different. These stones can vary in value but are generally highly prized when they display a balanced mix of colors with good saturation.
5. Black
Black kyanite, with its dark, opaque appearance, is less commonly used in jewelry but is valued for its grounding properties in metaphysical circles. It’s often found in blade-like formations and is appreciated more for its crystal habit and energy than for traditional gemstone use.
6. Orange and Yellow
The rarest colors in kyanite are orange and yellow, which occur due to unique trace element combinations. These colors are highly unusual and sought after by collectors, often fetching higher prices due to their scarcity.
Color Uniformity and Saturation
Uniformity of color and saturation are critical in evaluating kyanite’s quality. Gems with even color distribution and strong saturation are more valuable and sought after. Color zoning, or areas of different colors within the same crystal, can affect a gemstone’s appeal and value, although some collectors may find this characteristic interesting.
